Removed duplicate code for converting a string of hex characters into a byte array, done both in MonetBlob.create() and in MonetResultSet.getBytes().
Extended MonetBlob with utitlity method: hexStrToByteArray(final String hexString) such that it can be called from both places.
Also added an extra constructor MonetBlob(String hexString) which replaces the utility method MonetBlob.create(String hexString). This makes it more orthogonal with MonetClob.
